CASH REGISTER Fi led March 15, 1928 7 Sheets-Sheet '7 Berni: M. Shipley WWW Patented May 12, 1931 UNITED STATES PATENT OFFICE BERNIS M. SHIPLEY, 0F DAYTON, OHIO, ASSIGNOR TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF MARYLAND CASH REGISTER Application filed March 15, 1928.

This invention relates to improvements in cash registers, and more particularly to indicating mechanisms for cash registers of the type shown and described in Letters Patent of the United States, No. 876,295, issued to T.'Carney on January 7, 1908.

One of the objects of the invention is to provide an indicator of small diameter, to occupy a minimum of space in the machine, but with characters of maximum size thereon, so that the characters can be seen from a distance, and to this end, the indicators are each formed of two polygonous members arranged in tandem and torsionally offset relatively to each other, each member having a series of characters, the indicators being axially shiftable to display a character of either series.

Another object is to provide a novel means to maintain the indicator in its axially shifted position, said means being adapted to co-operate with the angle of one of the polygonous members of the indicator. A further object is to torsionally offset the two polygonous members of the indicator, in such a manner, that the angles of one polygon overhang the center of the faces of the other polygon, to provide projections with which cooperates the means for maintaining the indicator in its axially shifted positions.

Still another object of the invention is to so arrange the indicator in relation to the sight opening, that the faces of the polygons, which bear the indicating characters, are close to the opening, to present a flat surface with a maximum angle of vision, whereby the indicator can be seen from a wider range in the place of business in which it is used.

Another object is to provide a cash register with novel indicators which present the amounts set up in proper decimal order to the eye from both front and rear, thus providing an indicator which can be read at a glance.

' A further object is the provision of indicating mechanism for key-operated machines, which Will impose the minimum amount of load on the keys for its operation.

A still further object is the provision of novel and simple, yet very rapid and effective,

Serial No. 261,996.

means for adjusting the indicators to correspond with the keys depressed.

Still another object is the provision of novel means to prevent over-running or overthrow of the indicators when being set to their indicating positions, and to hold them where set or adjusted.

Another object is the provision of novel means to control the aligning mechanism'for the indicators.

A further object is the provision of novel transaction indicating means.

Still another object is the provision in a key-actuated machine, of a novel form of indicating mechanism, whereon the digits of the amount registered on the machine will appear on both front and rear of the machine in their natural order.

Vith these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

' General description The mechanism disclosed herein includes an illustrative keyboard arrangement, a differential mechanism, indicator mechanism, and a means, known in the art as a minimum movement device, foradjusting the indicators directly to the new position, as determinedby the value of the depressed keys, Without first returning to zero. A somewhat similar mechanism is disclosed in Letters Patent of the United States, No. 1,619,664, issued to F. L. Fuller, et al., on'March 1, 1927. V

The particular mechanism selectedv to illustrate one form of the presentinvention is a key-operated or press-down key machine, equipped with two full sets or groups of keys, to register units and tens of cents, and a single dollar key.

As in all machines of this type, depression of an amount key controls the indicator mechanism, adds the amount on a totalizer, and effects the imprint of the amount. In the present instance, the invention relates to the indicating mechanism and its control by the keys, therefore the totalizing and printing mechanism have been eliminated.

The indicating mechanism, which is one of the novel features of this invention, includes two groups of rotatable, multiple faced inclicating inemhers, one for thewfront of the machine and the other for the rear, and each indicator of a group is formed of two sections arranged one over the other in tandem, each section having thereon half. of the ten digits of the decimal order., In, the formshown, theodd digits are placed on the lower section,

and the even digitson the, upper section, of each indicator. v

Each indicator is constructed to carry maximum sized characters, but the indicator itself is offa min mum size in diameter, so-asto take up very little space intheregisterq The indicators, furthermore, are arranged to re quire very little movement when rotating from one position to the other, and this, to gether with the fact thatthe lnCllQatOlS are light in weight, reduces the'momentum thereof to a minimum.

vThe size and lightness of weight isobta ned by forming the indicators of two sections, each section being.pentagonalinshape, thus providing live surfaces on. each section for the characters The completeindicator,

comprising two pentagonal sections, which sections, however, are preferablymade of one piece of tubing swaged to theshape disclosed, provide ten surfaces for characters, which is suflicient in machines adapted to calculate decimai amounts, for one bank of amount keys running from Zero to nine. An indicator of similar shape, that is to say, the

shape of the indicator itself, as distinguished from its mode of operation, is dlsc-losedln Letters Patent of the United States, No. 5 17,5588, issued to C. Price on October '15,

1895. However, the indicator disclosed in the patent to Price, differs in many essential particulars from that disclosed herein, the infldicators of the patent perform in a different manner. Furthermore, the individual indicators ofithe patent are adapted for simultaneous indication to the front and back of the machine, as d stlngulshed from this nvention wherein separate sets of indlcators are provided for the front and back of the. machine,respectively. Also,inthel?ricepatent, each indicator is provided with two sets of the same five characters, whereas each com-.- plete indicator herein disclosed, 18 provided with one'setof ten characters. Other d fferences will appear hereinafter.

by the respective keys.

Inasmuch as each indicator has two sections, it is necessary to arrange not only to rotate each'indicator to bring the proper charartcers into a plane parallel with the sight openings in the machine, but to shift each indicator axially to bring the characters on the lower section, for example, into visible position at the sight openings. To this end, each indicator is mounted to shift axially along a rotatable shaft, and-to rotate therewith. The mechanism is preferably constructed to lift and rotate the indicators simultaneously. Thus, by the time the indicator is rotated to the proper position, it is shifted into position to expose a character on the lower section of the indicator, when such a character is selected by the rotary movement of the shaft. When the character to be exposed is on the upper section of the inclicator, the indicator is permitted to drop back to its lower position after it has been shifted. It is to be understood that the invention is not limited to the simultaneous shifting and rotation of the indicators, as it is apparent that the indicators can be first rotated and then shifted, or vice versa. In any event, the final result is the same. However, by operating the two mechanisms simultaneously a saving of time is effected in the operation of the various elements of the machine.

The indicators disclosed are particularly well adapted to machines of the press-down key type, as for example, in machines of the type disclosedin Letters Patent of the United States, No. 87 6,295, issued to Carney on Jannary 7, 1908, and is herein disclosed as shown applied to a machine of a somewhat similar type. But it is not intended to limit the use of this invention to machines of this type, because it can be adapted to any machine wherein indicators are desirable.

In machines of the Carney type, the usual indicators provided in the past, consist of individual tablets, assigned to and operated One disadvantage of this indicator is that it cannot be readily read, as for example, when registering the amount of one dollar and seventy-five cents ($1.75), the indication reads as follows:

$1. .70 .05, whereas on the indicator of the present invention, the indication appears in proper form, as shown in Fig. 1 of the drawings. A

' further disadvantage of the tablet indicator is that when both front and backindicators are desired, the back indicator of the Carney type reads backward. Using the above example, the back indicator reads as follows: .05 .70 1 $1.

The indication of the present invention can be read equally well from the front and back of the machine.

By using indicators with ten flat faces instead of a round indicator, the angleof vision ii in which the indication can be seen is greater.

The flat surfaces permit the characters thereon to be brought close up to the sight opening, leaving only enough space between the lass in the sight opening and the indicator to permit free rotation of the indicator. Thus it is apparent that the indicator can be observed from a greater angle than is possible with any of the above enumerated types of indicators. This is a very important feature in indicators for cash registers, since the indicator is intended to be displayed to the customer and to the public, and therefore, by constructing and arranging the indicators in relation to the sight openings, to give a maximum angle of vision, the customer and the public can better observe the amount thereon from all parts of the store.

Detailed description Key board The forward ends of key levers 35 project through vertical slots 47 formed in the frontwall of the casing or cabinet 44. These key levers are arranged in denominational groups from right to left and carry the usual key pops designating the values assigned to the Keys.

As disclosed in the present application, the

'- machine is provided with three banks of amount keys. The units of cents keys and the dime keys are of full complement, that is from 1 to 9 cents and from 10 to 90 cents, respectively. However, in the keyboard disclosed herein only one dollar key has been shown. This keyboard arrangement is illustrative only, as any keyboard'arrangement can be used.

. Dz'fierential mechanism Allof the keys 35 are pivotally mounted on a rod 36 supported in the side frames 30 and 31.

The differential segments 39, on their clockwise travel, carry the upper end of the beam actuator 53 with them, and the stud 52 of the beam actuator which lies in the heart-shaped cam slot 64 of the minimum movement segment will tend, at some point in its rocking travel, to rock the minimum movement segment 50 with the differential segments 39, providing the digital positions to which the differential segments 39 are to be set, is of higher value than that set up on the previous operation.

In Fig. 2, the minimum movement device 50 is in its zero position, and any clockwise travel of the differential segments 39 will rock the beam actuator 53 and with it the minimum-movement device 50, through the oppositely projecting studs 52.

Since the axes of rotation of the differential segments 39 and the beam actuator 53 are not coincident, the rod 40 might prevent the operation of the machine, were it not for the fact that the narrow apex of the heart-shaped opening 331 in the beam actuator 53 is disconnected from the rod 40 just prior to the rocking of the beam-actuator by the differential segments 39.

The beam actuator continues its upward thrust due to the shapes of the cam slots 62 in the arms 61, coincident with the clockwise rotation of the differential segments 39, the upper rear end of the beam actuator being guided by the cam slot 51 in one of the differential. segments 39, and swinging around the rod 40 as it travels rearwardly and upwardly, until the right-hand stud 52 (Fig. 2) in the beam actuator is in the left-hand end of the cam slot 51 in its differential segment During this movement the left-hand stud 52 of the beamactuator cooperates with inner walls of the heart-shaped cam opening 64 in its minimum movement device 50, to rock the minimum movement device, until finally the left-hand stud 52 enters the terminal 65 of the cam opening 64, at the end of its rearward stroke to adjust the minimum movement device 50 to a position determined by the position to which the differential segment 39 has been adjusted by the depres sion of its key 35. i

The cam opening 64, 65 in. the minimum movement device 50 is so arranged that when the left-hand stud 52 co-operates with the in rod 40, as the dif ner wall thereof, the minimum movement device is adjusted from its last adjusted position to its new adjusted position through its shortest path, as is well known in the art.

Indicator The dimes indicators are set up by the minimum movement device 50. A pinion (Figs. 2 and 7) secured to a transmission shaft 71v meshes with the teeth of the minimum movement device 50, in the dimes bank,

the shaft also having secured thereto a com panion pinion 72 in mesh with an indicatordriving se ment 73, mesh with a pinion 74. The transmission shaft 71 may be conveniently journaled in the side frames 30 and 31. The pinion 74 is secured to a bevel pin ion 75, both of which pinions are mounted to rotate on a rod 76 supported in suitable ears 30 (Fig. 4) depending from the bottom of a bridge piece 93 extending between and secured at its opposite ends to the side frames 30 and 31 (Fig. 7,. The bevel pinion meshes with a bevel pinion 77 mounted on the lower end of, and adapted to rotate, a vertical. shaft 7 8, on which the indicator 79 for indicatin toward the front of the machine is slidably mounted. The vertical shaft 78 is square and provides a convenient means to rotate the indicator 79 and to permit axial movement thereof on the shaft. The lower end of the indicator shaft 78 is round (Figs. 4 and 7) and is supported in a step bearing formed in the brid piece 93, the upper end of the shaft being round and similarly journaled in a tie bar 255 secured to indicator side frames 161, 162 extending upwardly from the ends of the bridge piece 93.

It is apparent that any adjustment of the minimum movement device 50, as determined hy the value of the depressed key 35, is transmitted to the shaft 7 8 by the pinion 70, shaft 71, pinion 72,- indicator-driving seg- 7 3, and pinions 74, 75 and 77, to rotate the dimes front indicator 7 9 to its position of adjustment according to the value of the key depressed.

A companion indicator 89 (Fig. 6) is provic ed for indicating toward the rear of the machine. This indicator is rotated to position by mechanism connected to the front indicator 79. To this end, a pinion 90 (Fig. 6) is mounted on the vertical shaft 78 and meshes with a segment 91, pivoted on a stud 92, carried by the bridge piece 93 (Figs. 2, 4, 7 and 8). The back indicator 89 is mounted on a vertical shaft 94 similar to the vertical shaft 78, and a pinion 95 being mounted on shaft 94 meshes with the segment 91. Thus any rotatin movement imparted to the front indicator 7 9 is transmitted to the rear indicator 89 by the pinions 90 and 95 and the intermediate segment 91, so that any character which may be set up to be read from the front bf the machine, will also be set up to be 'read from the rear of the machine. Convenient sight openings 96 are provided in a sight plate97 for-exposing the indicators.

Q The mechanism for transmitting rotary movement to the units of cents indicator will 1 next be described. Each key in the units of -centsbank is provided with acam slot like the cam slots 37 (Fig. 2) forthe keys in the dimes bank. .Thecam slots in the units of cents denominational'group of keys difieren- Y tially. rock a universal rod 100 (Fig. 7) simb ank, and carried by a pair of differential segments 101 similar to the differential'segilar to the universal rod 38 for-the dimes merits 39. F or structural reasons, it is de sired to have all of the beam actuators andv .the minimum ,movement devices located 7 substantially in the center 1 of the machine I and adjacent each other.

2 mum movement device 102 for. the units of cents bank. of keys 35 is located adjacent the left-hand differential segment 101 for. such 7 (bank of keys. -.The left-hand differential segment 101 for the'units of cents bank has a cam slot similar to'thc cam slot 51 of. the

jdiiferential segment 39 (Fig.2), and a beam jactuator 120 (Fig. 7), similar to-the beam actuator 53 (Fig. 2) carries oppositely pro-,

I jectingstuds 121 (Fig. 7) one of which projects into the cam slot in the differential seg- ,ment,101, and thecother of which projects into the heart-shaped cam opening of the minimum movement device 102. The operation of these parts is exactly the same as that described for the dimes bank, and for this reason, no detailed descriptionof the operation ofthecents minimum movement de-.

vice 102 will be given. The description for the cents bank will be limited to the method of transmitting movement from the minimum movement device 102 to the cents indicator. The minimum movememtv device 102 (Fig. 7), meshesw1th a pinion 103 secured to a :shaft 1journaled in any convenient manner on the side frames and- 31. Near thev right-hand end of the transmission shaft 104 is a pinion 105 in mesh with a segment 106 similar to the segment 73 (Fig. 2) and pivoted on the shaft .40. The segment 106 meshes with a pinion 107 loosely mounted on the shaft 76. .Sleeved to the pinion 107 is a bevel pinion 108 in mesh with a bevel pinion 109 mounted on a vertical shaft 110 (Fig. 6) upon ...Wl1iCl1 the cents front indicator 111is slidably -mounted. Thus, any movement. im-

4 parted to the minimum movement device I 102, under control of a centskey, is transmitted to the indicator 111 through the. pinion 103, transmission shaft 104, pinion 105, segmcnt 106, pinion 107 and, bevel pinions 0 and 109. r

An indicator 112 (Fig. 6) is provided to 1 indicate the cents at the rear of the machine,

and isad justed by connections from the front' s a i di at S f -1 0- A P n on Hence the mini-,

. newt-6 mounted on the vertical indicator shaft 110 (Figs. 6 and 12) meshes; with a segment 1141 journaled on the bridge pie'ce;93 at 116,;and having pivoted thereto one end of a link 115.

Theopposite end of the link 115 is pivoted to a segment 117 loosely mounted on astud 145 pinion 118 mountedon the vertical indicator shaft 1119 for the rear cents indicator 1 12.

Thus any adjustment ofthe units ofv cents front indicator 111 is transmitted to the units of cents rear indicator 112 by the pinon the bridge piece93 and meshing with a ion 113 segment 114, link 115, segment 117 and pinion 118.

The machine disclosed herein is provided required for the dollar keys Instead, a stud 125 (Fig. 7) is mounted directlyaon a diiferential segment 126, similar .to the left-hand diiferentialsegment 39 for the dimes bank. A pinion 127 meshes with the differential segment 126, the pinion 127 being secured to a suitably j ournaled shaft 128 having-mounted thereona pinion 129 in mesh witha pinion,

ential 132 and the minimum movement de vice 133 andhaving the oppositely projecting studs 150-entered in the cam slotof the differential and the heart-shaped cam opening in the minimum movement device,respectively. r V t The method of adjusting. the minimum movement device 133 is like that described for the adjustment oftheminim um movement device for the dimes bank.

Tl1e minimum movement device 133' for the dollar bank meshes with a1pinion13 1 loose on a shaft 135. A pinion 136 .secured to the sideof the pinion 134 meshes with a pinion 137. loosely mounted on the shaft-76.

EA bevel pinion 138 sleeved to the 31111011137;

meshes with abevel pinion 139.1nounted on theverticalindicator shaft 140. ;-The dollars frontaindicator 1 11 is slidablymounted on. androtatable. with the shaft 140, and therefore, any ad ustment imparted to the minmnm 111OV8II1BIlt,Cl8V1CG 133 underthe control of the depressed dollar key, is transmitted to the dollar front indicator. 141 by the pinions134, 130,137, 138 and 139.

Any, reta r m vem nt giv th in e t with only, one dollar key. .For this reason, no universal rod, like the rod 38 (Fig. 2), is

shaft 140 (Figs. 6 and 12) is transmitted to a rear dollars indicator 142, by the following mechanism. A pinion 143mounted on the dollars shaft 140 meshes with a segment 144 pivotally mounted on the stud 145 projecting from the bridge piece 93. A- link 146; pivoted at one end to the segment 144, is connected at itsopposite end to a segment 147 pivoted on the stud 116. The segment 147 meshes with a pinion 148 mounted on a vertical shaft 149 which carries the rear dollar indicator 142. I I r Thus, any movement given to the dollars front indicator 141, is transmitted to the rear dollarsindicator 142 by the pinion 143, segment 144, link 146, segment 147 and pinion 148.

For convenience, the indicator shafts are made square. However, it is not intended to limit the invention to a square shaft, inas- 'much as any convenient form of shaft may be used. Since it isnecessary not'only to rotate the indicators to position the proper characters adjacent the sightopenings, but it is also necessary to axially shift the indicators relatively to their-shafts, a square shaft forms a convenient method of obtaining the results.

The indicators disclosed are. preferably formed of two hollow pentagonal members arranged in tandem and offset torsionally.

These two parts are formed up of one piece of tubing, swaged to the shape disclosed. The pentagonal parts are torsionally offset so that the angles of one pentagonal member will bisect and overhang the centers of the faces of the other. This construction affords the largest possible sized indicia on the indicator, and occupies 'a minimum amount of space in the machine. This result-is furthered by arranging the indicator characters in two series, upper and lower. However, this arrangement of, characters renders it necessary to not only rotate the indicators to position the proper characters opposite the sight openings, but; also necessitates shifting the indicators axially on their respective shafts. I r

The numerals are convenientlyarranged so that all of the even numbers are on'the upper section or pentagon and the odd numbers are located on the lower section. By arranging the indicia in this manner, the indicators need be rotated only the distance equiv alent to one-half of the width of each face of the pentagon, to obtain ten positions of adjustment. 7

Indicator aligning mechanism An aligning mechanism is provided to maintain the indicators in proper alignment and in the positions to which they are rotated by'the depression of the keys. To this end, aligning disks 155 are provided near the upper ends of each of theindicator shafts 78, llOand 140 (Figs.-.4 and 9) for'one set of indicators, as the front indicators. The disks 155 are each provided with tennotches,one for each of the positionsto which the indicators may be set by the depressed keys. Rollers or detents 156 enter the selected notches at each operation of the machine to hold the disks 155 together with the indicator shafts and indicators from rotating after the indi cators have been adjusted. The rollers or detents 156 are carried by a bail 157 (Figs. 2, 5, 8, 9 and 18) having arms 158 and 159 secured to a shaft 160 pivotally mounted'in the upper indicator side frames 161 and 162 projecting upwardly from opposite ends-of the bridge piece 93 and supporting the tie bars 255 for the front and rear series of indicators. An upwardly projecting arm 163 (Figs. 8, 15 and 18) secured to the shaft 160 serves two purposes. One purpose is to provide a convenient means for attaching a spring 164, which, together with a companion spring 165 attached to the arm 159 provides means for maintaining the rollers or detents 156 in contact with the notches in the aligning disks 155.

Before the indicators can be rotated, the rollers or detents 156 must be disengaged from the aligning disks 155. To this end, the mechanism shown in Figs. 4 and 5 has been provided.

Bifurcated arms 170, one secured to each end of the key coupler 57 embrace studs 171 on one arm of bell cranks 172 pivoted onthe rod 40. Links 176 connect the remaining arm of each bell crank 172 with arms 174, pivotally mounted on studs 175 carried by the side frames 30 and 31... Vertically disposed links 177 connect the respective arms 174 with the opposite sides of. a reciprocatory skeleton frame 178 (Fig. 3) at 179, which frame raises and lowers the indicators in a mannerto be later described. The pivotal connections 179 between the links 177 and the sides of the reciprocatory frame17 8 extend through vertical guide slots 194 (Fig. 4) in the indicator side frames 1 61, 162, which slots enforce a rectilinear travel of the reciprocatory skeleton frame or cage. Each link 177 is provided with a slot 180 (Fig. 5)

into which projects a stud 181 mounted in a to lift the links 177 and with them the cage 17 8, the key on itsreturn to normal position enabling the links and cage to descend to their normal positions. As the links 177 rise during the depression of the key,.they rock the pawl carriers;182 (Fig. 5)

due to the'slot'an'd pin connections 180, 181 therewith tocausethe pawls 184 to turn the nected to the outer ends of a pair of crossed levers 192 and 193- pivoted on the cross shaft 160. The cam disks 186 on opposite sides ofthe machine, at the beginning of their rotation, raisethe' rollers 189 to straighten the toggle links 190 and 191 and rock the I crossed levers192 and 193 in opposite direc- 5 and the arm 163.

tions. The levers 193 are each provided "with' a stud 195, (Figs. 5, 8 and 18), in the paths of the'arm 1590f the aligning bail 157 The springs 164 and 165, operating through the arms 163 and 159 respectively constantly tend to rotate the levers 193 in a clockwise direction,'thus maintainingthe toggle rollers 189 in contact with theca-m "surfaces187 of the cam disks 186. When the cam disks 186 commence to rotate 'as just -mentioned, and the rollers 189 are raised, the

levers 193, through their studs 195, rock the bail 157 counter-clockwise (Fig. 5) against the tensions of the springs 164 and 165 to disengage the aligning rollers ordetents 156 from the aligning disks 155. As the links 177, reach their extreme upward limits of a travel, they rotatethe cam disk-s 186 to bring a. recess in each disk opposite the toggle joints and rollers 189, whereupon the toggle links 190 and 191 flex or bend, under the tensions of the springs 164 and 165, the toggle rollers 189 dropping into the recesses of-the cam disks 186 which havebeen moved into the-paths of the rollers 189 by the links 17 7 and pawls 184, to permit the springs 164 and 165 to shift the aligning detent rollers'156- back into engagement with the disks 155, as shown n 9. e V

No aligning disks 155 or alignlng members have been provided for the backindicators,

this being unnecessary since the back indicators are directly connected to the front indicators, by the gear and linkage shown in Fig. 6, and therefore, if the front indicators are properly aligned, the back indicators are also properly aligned.

Indicator shifting mechanism The. foregoing description has been directed,1n the mam, to the means for rotating the indicators to position the proper numerals in line with the sight openings,'but inasmuch aseach indicator is provided with a single consecutive set of numerals arranged in two series on the respective upper and lowerpentagonally shaped sections located one-above the other, it is necessary to axially inside the shell.

two pentagonal sections of substantially equal length, the pentagon on one of the sections being formed as though offset torsionally relatively to the other pentagonal section, though there is no actual relative torsional displacement of the sections. In shaping the material to form the indicator shell with offset sections, alternating shoulders are formed at the upperend of the lower section and at the lower end of the upper section, as seen in section in Fig. 4, and in dotted lines in Fig. 6, such shoulders being separated by the thickness of metal only, and as one convenient means for attaching the indicator shells to their vertical shafts, each indicator shell'is provided withtwofive-armed spiders201 and 203 (Figs. 4 and '19), of proper size to fit These spiders are introduced into the indicator shell at its opposite ends, the outer ends'of the arms being angular' to fit in the angles and on the shoulders of their respective sections, the two spiders thus lying loosely in the shell, parallel W1tl1 EtI1Cl closely adjacent each other.

A hub 200 having a square bore to fit and slide upon the indicator'shaft, is reduced at its upper end to pass through registering openings formed centrally of the spiders 201 and 203, the upper spider 201 being conveniently staked, or otherwise fastened to the reduced end of the hub,.which hub is'fianged, as at 202,-to support and hold the lower'spider 203 in place;

This method securely fastens the hub 200 to the indicator shell in a simple andnovel manner. I v

The hubs 2'00 carrying the indicatorsare constructed to loosely fit and slidably move on the indicator shafts. When in lowermost positions, the ends of the indicator hubs 200 for thefront and rear seriesof indicators rest on collars 204 having circular bores encircling the indicator shafts, the collars being mounted on and projecting upwardly from channel bars 205 for the front indicators, and 206 for the rear indicators. 6 and 7 The indicator shafts extend upwardly through the channel bars 205 and 206, which bars are spaced; apart and secured at their opposite ends to the sides ofthe reciprocatory frame 178. As before mentioned, the sides of the reciprocatory frame 178 each have pivoted thereto the links 177 whichare raised and lowered by the key coupler 57 and connecting mechanism shown in Fig.4, at each operation of a key 35. i

Operation of the machine rocks the key coupler 57, which, through the bell-cranks 172, links 176,-arms 174 and links 177, raise and lowerthe skeleton frame or cage178, and wwith it the channel bars 205-.an'd.206,= to raise (See Figs' 3,4,

and lower the indicators on their indicator shafts.

Whenever any indicator is rotatably adjusted to bring a flat face of its lower section in parallelism wit-h its sight opening 96 in the sight plate 97, preparatory to displaying the character on such flat face, it isnecessary to raise the indicators and support in raised position such of them as have the character or characters desired to be exposed, on their lower sections.

As a matter of convenience and simplicity of construction and operation, it is easier to raise all the indicators at each operation of the machine, retaining in raised position only those indicators on which the desired character for display is on the lower section, the remaining indicators restoring to their lower positions, to expose the characters on their 5 upper sections.

The angles or corners on the lower'section of each indicator, readily lend themselves to the purpose of maintaining the indicators in their raised positions when necessary to expose the lower characters through the sight openings.

Cooperating with the corners or angles of the lower sections of the respective series of indicators are two supporting bars 210 (Figs. 5, 8 and 18) having lateral flanges or lips 211 projecting into thepaths of the corners or angles of the respective indicators. At the beginning of the operation of the machine when the elevating links 177 are raised, and

the cam disks 186 (Fig. 5) raise the toggle rollers 189 to straighten the toggle links 190 and 191, the flanges 211 are withdrawn from contact with the indicators when the indicators are in raised positions. The bars 210 extend between and are carried by the arms of levers 192, 192 and 193, 198,-that is, each bar connects the corresponding levers of each pair. When the elevating links 177 rise to rotate the cam disks 186 and rock the levers 192 and 193, to withdraw the indicator aligning rollers or detents 156, as heretofore described, the supporting bars 210 rock with their levers 192 and 193, respectively, to withdraw the flanges or lips 211 from cooperation with the indicators, and any indicators which may have been supported by the flanges, will partially return to their normal toggle joint rollers 189 drop into the recesses.

to the sight opening, the rear of the indicater presents an angle or corner overhang ing one of the flanges 211, and therefore, when the reciprocatory lifting frame 178 is lowered to withdraw the channel bars 205 and 206 from the elevated indicators, the overhanging angles or corners of those lower pentagonal sections of the indicators which present their flat faces to the sight openings 96, catch on the flanges 211, which maintain those indicators in raised positions to expose the characters on the lower pentagonal sections of the indicators through the sight openings.

If one Or more of the indicators are adjusted to present a flat surface of the upper pentagonal section of the indicator to the sight opening, then one of the flat faces on the lower pentagonal section is opposed to the flange 211, and since the flange 211 is not long enough to engage the indicator when a face is presented thereto, the indicator will drop as the channel bars 205 and 206 are lowered, and present a character of the upper pentagonal section of the indica-' tor to the sight opening.

Though the indicator disclosed in the present application is formed of two pentagonal sections, it is to be understood that the invention is not limited to such a specific form, inasmuch as any suitable polyhedral member can be used equally well with the mechanism disclosed. If, for example, fourteen characters are to be indicated by means of a single indicator, then two seven-sided sections can be used and each of the sections of the indicator and the angles or corners of the lower torsionally offset section can cooperate with the holding means in exactly the same manner as the pentagonal-shaped member disclosed.

The mechainsm for imparting rotary movement to the indicators for selecting the character to be exposed operates substantially simultaneously with the indicator lifting or elevating mechanism, butit is not desired to limit the invention to this simultaneous operation of the mechanisms, inasmuchas means may beprovided for first r0- tating, and then shifting the indicators, or

for first shifting the indicators and then rotating them. However, it is more convenient to have these two mechanisms operate substantially simultaneously since it eflects a saving of time in the operation of the machine. This saving of time is especially important in press-down key machines where all the mechanisms are operated by depression and return of the keys.

indicator 251, each bearing the words Cash I Cash and N 0 Sale imifcation A special indicator is provided for designating the instant transaction. Such indica-.

tor may bear the word Cash or'the words No Sale, for example. In the present form,

the special indicator mechanism is arranged to normally present the word Cash to the sight opening when the No Sale key is not maticallyreleases, and a spring returns the indicator to normal position to exhibit theword Cash at the sight opening.

There are two special indicators,the front indicator 250 (Figs. 13 and 15"), and therear and No Sale. The indicator 250 is provided with a pinion 252 secured to a horizontal shaft 253 to which the indicator 250 is also secured. The horizontal shaft 253 is journaled in the indicator. side frame 162 and a hanger 25 1 depending from the cross bar 255 supported by the indicator side frames 161 and 162. The indicator 251 for indicating the transactions toward the rear of the chine is supported by a similar horizontal dicator side frame 162 meshes with both pinions 252 and 256. A control arm 262 is fast with the double-ended segment 258, and one end of a spring 260 is connected thereto, to normally rotate the double-ended segment 258 in a counter-clockwise direction until arrested by a fixed stop 268, at which time the word Cash will be displayed. The upper end of the spring 260 is connected to a stud 261 carried by the indicator side frame 162.

When the control arm 262 is in normal position, a roller 265 on the lower extremity of the control arm lies adjacent an upwardly extending. finger 266 of a forked pitii' an 267.

Thus, with the pitman 267 in itsnorinal position, as shown in Fig. 13, thespring 260 holds roller 265 in contact with the upper extension 2660f the pitman.

A No Sale. key 270 operates the p'itman' 267, the movement of which is guided by a slot 269 and a suitable pin. The .No Sale key is pivoted on the same rod 36 on which the amount keys 35 are pivoted.

'Depression' of the No Sale key 270 lifts the pitman 267 tobring a cam surface 271 on. the finger 266 into contact with the roller 265 on the control arm to rock the control special indicators 250 and 251 to presentthe words No Sale to the si 'ht ooenin s.

. b L b.

Since the double segment 258 is normally spring-actuated in clockwise direction, it is necessary to provide a latch to maintain the indicators 250 and251 in their No Sale positions, so that, upon release of the No Sale key 270, the double-ended segment 258, and

the special-indicators will be retained where adjusted. This is necessary because it is at enable to maintain the words No Sale at upper armof which carries a stud 288 pro- 7 jecting througha slot 289 in the before mentioned spring-actuated indicator detent-c0ntrolling arm 163. A spring 290, stretchedbetween the stud 288 and a stud 291 on the arm 163, normally tends to hold the latch 285 in engagement with a notch 292 in the disk 287. r The before mentioned restraining stud 195 (Figs. 8 and 15), carried by the lever 193 and I extending across the indicator 'detent bail operating arm 163, also'lies in the path of the latch. 285. Since the stud 288 on the latch 285 projects into the slot of the arm 163, and i is held in position by the spring290 also connected to the arm 163, it is apparent that when the inacnine is operated and the lever 193 is rockedcounter-clockwise (Fig. 15), the stud 195 rotates, not only. the arm 163, but also the latch 285 in counterclockwise direction to withdraw the nose of the latch 285 from, a notch 292 of the disk 287 in which the latch normally engages to maintain the indicator in the"C ash position.

Uponudepression of the 270, the cam edge 271 on the finger 266 of the pitman 267 rocks the doubleended segment 258 to turn theindicators 250 and 251 in clockwise direction 15) until the notch 286 of the locking disk 287 is positioned in the path of the latch 285. At the end of the down stroke ofthe No Sale key, the arm 163 and latch 285 are released, as

above described, and then the latch 285 drops 2 I intothe notch 286 to maintain the indicators s in position to'eXpose the words"No Sale; However, upon the next operation of the machine, when the cam disk 18,6,rotates in the manner heretofore described, to rock thelever193 in counter-clockwise direction, to

swing the arm 163, the arm 163 will rock the latch 295 in counter-clockwisedirection, and

releasethe special indicators to the action of the restoring spring 260 (Fig. 13). The re- 1:.

storing spring 260 rotates the double-ended segment 258 in clockwise direction (Fig. 13) until the segment is arrested by the stud 268 No Sale key i in the side frame. When in this position, the 2 special indicators position the word Cash atthe sight openings, and the latch 285 engages the notch 292 as shown in Fig. 15. j

. From the above it will be apparent that the spring 260 .always returns the special indicators to expose the Word Cash, whereas the cam edge 271 on the pitman 267 positively moves the special indicators to the No Sale ppsition, as determined by the No Sale key 2 0. V

Operation In using the machine, the items are entered by depressing the appropriate amount keys 85 (Fig. l) which adjust the differential mechanisms to rotate the indicators to select the proper characters, and, also lifts the indicators to determine which of the two sets of characters thereon are to be exposed at the sight openings.

Depression of key 35, through the diifer- 'ential slot 37 in the rear end thereof, adjusts the, differential segment 39 according to the value of the key depressed, and the minimum movement actuator 53 operates to adjust the minimum movement device accordingly.

The minimum movement device rotatesthe corresponding front and rear indicators to position the characters to be exposed in line with the sight openings, the indicators moving directly fromtheir last adjusted posi- "tion to the new position. Substantially simultaneously with the rotation of the indicators to select the characters for indication, the indicators are raised to determine whether or not the upper or the lower characters'are to be exposed at the sight openlngs. By the time the 1nd1catorsare elevated to their up permost positions, the differential rotationof the indicators is completed, and the indicator elevating frame 1'2'8 returns to its normal low 'est position as the depressed key restores.

Also the means 210 211 which su aports the q 7 v 7 a I indicators in elevated positions becomes effective.

metrically opposite the flat faces bearing the characters to be displayed, rest on the sup- ;porting members 210,211, which will hold the indicators in'their elevated positions.- Howthe lower sections of those same indicators present flat faces to the supporting means 210,

211, so that as the elevating frame 178descends with the return ofthedepressedkey, the indicators descend therewith, escaping past the supporting means 210,211 and positioning the selected characters on the upper sections of the indicators opposite the sight openings.

The aligning device 157, 158 'moves into *position to maintain the indicators against If characters on the lower sections of the indicators arefto be exposed in the "'"sight openings, the indicators will settledown until the angles of theindicators dia displacement after they have been difierentially adjusted and positioned according to the value of the depressed key.

Special indicators 250, 251 having the words Cash and No Sale indicate wheth- I er a cash transaction or a no sale transaction is effected. These indicators normally indicate the word Cash in the sight openings and are heldthere byaspring260. When the No Sale key is depressed, the indicators 7 are positively adjusted to the No Sale pofor unit assembly, the indicator mechanism" and the differential mechanism, 'heing independently assembled as units, and subse quently assembled together in the machine.

Obviously, this invention will include an arrangement of indicators having the rows of characters arranged side by side, the indicators being shiftable horizontally to expose a character in one row or the other.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment indicator to expose the selected character.
